2.2 Hardware Installation Hardware installation simply involves in connecting the Logic Analyzer to your computer with the included USB Cable as shown in Figures 2-4 and 2-5. 1. Plug the fixed end of the cables into the LA (Fig. 2-1). Fig. 2-1 2. Plug the loose ends into the connectors on the circuit board to be analyzed (Fig. 2-2). Note: The following sequence must be observed when connecting the connectors into the circuit board: A0 = Brown, A1 = Red, A2 = Orange, A3 = Yellow, A4 = Green, A5 = Blue, A6 = Purple and A7 = Gray. Fig. 2-2 3. The circuit board must be grounded to the Logic Analyzer with the black Ground Cable (Fig. 2-3). Fig. 2-3 4. Plug the square end of the USB cable into the Logic Analyzer (Fig. 2-4). Fig. 2-4 5. Plug the thin end into the computer (Fig. 2-5). Fig. 2-5 21 FM07I4A
At this point, the computer should be able to detect the Logic Analyzer and finalize the installation for hardware connection. For further information, refer to the Troubleshooting and Frequently Asked Questions (FAQ) chapters in the User Manual.

2.3 Tips and Advice 1. When testing a circuit board, make sure that the internal sampling frequency (within the Logic Analyzer) is at least four times higher than the external board frequency. 2. If the signal connector does not work well with the pins on the test board, try to use the supplied probes. Fig. 2-8: Probes Supplied with Zeroplus 3. Usages of probes 3-1. Take the loose end of the cable and insert it into the clip (Fig. 2-9). Fig. 2-9 Fig.2-10 3-2. Compress the probe as shown to reveal two metal prongs (Fig. 2-9). 3-3. Place the metal prongs on a metal connector on the testing board and release the fingers so that the prongs can grip the metal connector (Fig. 2-10). 4. The Logic Analyzer will connect to the Zeroplus server for software updating automatically if internet is available. 5. Unwanted signals can be filtered out by using the Signal Filter or Filter Delay function. 6. During long-time measuring, Compression would make memory work more efficient. 7. Trigger condition depends on the testing board. If triggering does not work well, try to narrow the trigger conditions and optimize them repeatedly. 8. If testing board s frequency is lower than that of Logic Analyzer, users shall sample signals according to the external clock. 9. When external clock is used for sampling, users could filter extra signals with the Signal Filter function. 10. Unused channels could be removed from the Bus/Signal column in the dialog box of Channels Setup(on the popup menu of Bus/Signal column). 23 FM07I4A

The amount of the acquired data that can be stored by the Logic Analyzer depends on the amount of the allocated RAM. The total depth of the memory for the LAP-A/C is 128K Bits in each probe. If the Logic Analyzer starts gathering data with a 128K memory range, it will take a long time to find the required information. In order to avoid spending a lot of time gathering data, select a smaller RAM Size. The RAM Size options are 2K, 16K, 32K, 64K, 128K and 256K. So, if gathering data with 128K takes a long time why does 256K make sense? The reason for this extra RAM Size is to cope with the fact that a few of the 1~16 channels may have a large data input. Tip: Clock Source Asynchronous Clock Use the pull-down menu to choose the speed of the clock on the board being tested. The sampling frequency should be more than 4 times higher than the signal to be measured so that the waveform duty cycle depiction will be accurate. 34 FM07I4A
Choose the frequency of the clock on the board of the Logic Analyzer. Select External Clock to acquire data through external sampling. Choose either Rising Edge or Falling Edge to execute the analysis process. According to the users input the value of external frequency in software, the software can count the relevant value about signal mode and frequency. For example: the value of the message, the time scale and the zoom in and out will be the value of time mode. Connecting the Synchronous Clock Use one of the single connecting cables to put one end on the testing board and the other in the LA as shown in the diagram opposite. Synchronous Clock of LAP-A/C Tip: Compression Check the box to compress all the data. Compression is used to compress acquired data through a lossless compressor. The purpose of this compression is to place more data in a limited memory than in an actual memory. The compression rate of the Logic Analyzer can be up to 255 times. This means that the maximum acquisition can be 32M Bits (128Kx255= 32M Bits) for each channel. The chosen capacity of the memory, 1MB, means that the maximum data being sieved out arrives at 1MB*255=255M Bits (Per Channel). Note: The rate will change depending on the data being analyzed. 35 FM07I4A
Tip: Signal Filter Setup Tip: Select the Signal Filter Setup from the pull-down menu of the Bus/Signal or click the icon or the Button on the Sampling Setup dialog box to open the Signal Filter Setup dialog box. Tip: There are three modes of Signal Filter configuration for each channel. Fig 3-22: Signal Filter Setup Dialog Box The function of Signal Filter is to use an alterable judgment circuit which can filter undesired signals in order to capture and store valuable data in the memory. When the combination of input signals from each channel meets the filter conditions, the section of acquired data will be gathered by the Logic Analyzer and stored in the memory. After storing the data, it will return to the Logic Analyzer s system and be displayed as a waveform. If the combination does not meet the filter conditions, it won t gather and store data. 1. = Don t Care means that the Logic Analyzer captures all signals from sampling. Fig 3-23: High and Low Levels It is the system default. 2. = High Level means that the Logic Analyzer captures and displays the input signals satisfying the high level. 3. = Low Level means that the Logic Analyzer captures and displays the input signals satisfying the low level. 36 FM07I4A
